How about a change at GM?

The 2017-2018 season is David Poile’s 40th NHL season as an assistant-GM or GM, and his 35th year as GM of a team. That’s a long time and he deserve praise for being able to last this long in pro sports. However, people don’t seem to recall that the teams he has managed have only made it past the second round of the playoffs TWICE in that time span, in 1990 with the Capitals and last year with the Predators! Yes, twice in 40 years.
